Abstract
The utility of hemispherically capped single-wall carbon nanotubes for use as scanning force microscope tips is investigated for the first t ime using molecular dynamics. These simulations show that [10,10] armc hair nanotubes recover reversibly after interaction with a hydrogen-te rminated diamond (111) substrate. The [10,10] tube exhibits two mechan isms for releasing stresses induced by indentation: a marked inversion of the capped end, from concave to convex, and finning along the tube 's axis.
